Expose the screen-locker's compliance and lock-decision state as read-only
MCP tools (screen_locker._mcp) so Claude Code and its subagents can query
workout status without shelling out to the CLI or opening the Tk window.
- _mcp.py: FastMCP stdio server. Read-only tools get_status, get_summary,
explain_lock, get_flags. Import leaf over stdout-free status functions
(gather_status, format_summary_line, explain_lock_decision, predicates);
logs to stderr. NO write/action tools by design — workouts are logged only
from RunnerUp-verified TCX data, never from a caller's claim. No tool
exposes the sync token or any HMAC key.
- .mcp.json + scripts/setup_mcp.sh: registration via a dedicated
~/.venvs/screen-locker-mcp interpreter; mcp is an optional-dep.
- 100% coverage of the new module; verified end-to-end over stdio.
